I know this post is very old but it works! Thanks so much I wanted a way to get my apps in the newsstand without them reappearing on my home screens everytime I restarted my springboard. This was the purfect tweak, this should be in the Cydia marketplace

Yeah I tried with System apps and it causes glitches and disappearances.

It does work perfectly on mobile applications though, thank you loads for this handy tip.

Yes. Indeed. I tried it just now. Doesn't work on stock apps, maybe tweaking the code will help. But that would be a lot of respringing. For me it wouldn't be that important. I just keep readers and forums apps in Newsstand. I tested it with Cydia apps though, that works just fine.
